The inverse of a quadratic parent function with a limited domain is given by the square root function, hence option C is correct.

Supposing we have a function y = f(x), to find the inverse, we exchange x and y, and isolate y.

The quadratic function is:

[tex]y = x²[/tex]

Exchanging and isolating y:

[tex]x = y^2[/tex]

[tex]y^2 = x[/tex]

[tex]y = \sqrt{x}[/tex]

[tex]f^{-1}(x) = \sqrt{x}[/tex]

Hence option C is correct.

Answer:

25

Step-by-step explanation:

c^2=a^2+b^2

where c = hypotenuse

so, x^2 = 24^2+7^2

x^2 = 576 + 49

x^2 = 625

x = square root of 625

The approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Here, given equation; (we are using n in place of t)

          -5.e¹⁰ⁿ = -30

      On dividing -5 both sides, we get

           -5.e¹⁰ⁿ/-5 = -30/-5

                e¹⁰ⁿ  = 6

 Taking 'ln' on both side, we get

             10n = ln 6

              n = (ln 6)/10

              n = 1.791759/10

              n = 0.179

Thus, the approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.

Q10

Answer:

9.  x = 200  and  y = 100

10.  x = 68  and  y = 99

Step-by-step explanation:

Question 9

The measure of an arc is the measure of its central angle.

⇒ x = 200

This is a non-cyclic quadrilateral as not all its vertices touch the circumference of the circle.

The angle at the center is twice the angle at the circumference.

⇒ y = 200 ÷ 2

⇒ y = 100

Question 10

This is a cyclic quadrilateral as all its vertices touch the circumference of the circle.  

The opposite angles in a cyclic quadrilateral add up to 180°.

⇒ x + 112 = 180

⇒ x = 68

⇒ y + 81 = 180

⇒ y = 99

The quotient when 48a³bc²is divided by 3abc will be 16a²c.

The information given is that we should find the quotient of 48a³bc² ÷ 3abc.

This can be expressed as:

48a³bc² ÷ 3abc = (3 × 16 × a³ × b × c²) / (3 × a × b × c)

= 16a²c

In this case, the quotient when 48a³bc²is divided by 3abc will be 16a²c.

The expression g = 2hm can be written as in terms of g and h when m is the subject is m = g/2h.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

g  = 2hm

To make m as the subject and solve it:

Divide the above expression by 2h on both sides:

g/2h = m  or

m = g/2h

Thus, the expression g = 2hm can be written as in terms of g and h when m is the subject is m = g/2h.

Answer:

16

Step-by-step explanation:

The range is the distance between the largest number and the smallest number. To find the range, you take the smallest number and subtract it from the largest number. In this case, the smallest number is -9 and the largest number is 7. 7 minus -9 is a double negative, so you can also do 7+9=16. 16 is the range.

For both problems, we can use the section formula.

1) [tex]P=\left(\frac{(1)(1)+(5)(-9)}{6}, \frac{(1)(8)+(5)(3)}{6} \right)=\boxed{\left(-\frac{22}{3}, \frac{23}{6} \right)}[/tex]

Answer:

b = 1/3

Step-by-step explanation:

The general structure of equations in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept.

The given equation is already in slope-intercept form. In other words, you have already been given "m" and "b". Therefore, the value which corresponds with the y-intercept is (1/3).

f(x) = mx + b

f(x) = -(2/9)x + 1/3

A circle can be characterized by its center's location and its radius' length. The correct option is A.

A circle can be characterized by its center's location and its radius' length. Let the center of the considered circle be at (h,k) coordinate and the radius of the circle be 'r' units. Then, the equation of that circle would be:

(x-h)² + (y-k)² = r²

The given graph is the graph of a circle that has its origin at (0,0) and has a radius of 4 units, therefore, the equation will be,

(x-0)² + (y-0)² = 4²

x² + y² = 16

Multiply both the sides of the equation by 2,

2x² + 2y² = 32

Hence, the correct option is A.

The values of x and y from the figure are 22.5 and 10 respectively

The angles that meet at a point X are equal and vertically opposite

From the diagram shown

6x - 5 = 8x - 50

6x - 8x = -50 +  5

-2x = -45

x = 22.5

Similarly

2y + 30 = 3y + 20

2y - 3y = 20 - 30

-y = -10

y = 10

The type of data that would be best displayed in a dot plot is the correspondent to the third option.

A dot plot is a plot where in the horizontal axis different numbers or properties (discrete set, usually we want smaller ranges, just so the graph are easier to read.) are marked, and above these, we mark dots, that represents how many times these are repeated on the data set.

We don't want large ranges (like in the first option 725 to 2450) because it means that we need to mark 725 points, or we need to find a common factor so each point represents more than one unit.

So, we need to have discrete data and with ranges not to large. The only option that meets both conditions is the third one, where on the horizontal axis we would have each of the 15 school dental clinics, and the dots would represent the number of dentist volunteering on each of them.

Then the correct option is the third one.
